The builders of the Jinhai Bridge Modeling Sword Section sprint towards the goal of the next month of Helong

The reporter learned from the China Railway Bridge Bureau that the section of the Jinhai Bridge Gan Dao is currently promoting the setting of the last 5 prefabricated steel beams, and strives to achieve the goal of Helong at the end of August.

The main bridge of Jinhai Bridge is a four -tower cable bridge. The main tower stands on the waterway of the Pearl River Portal Sword door. The steel beam needs to set the process through the asynchronous rack, set up a piece on both sides of the main tower, and finally the steel beams connect the four main tower together, and the cable bridge can be achieved. The work of steel beams is an important process, which is like adding a "scale" to the balance. It is necessary to accurately hang up the weight to ensure the balance of the main tower of the bridge. When setting up, not only requires the right tide position, but also temporarily seal the surrounding waters. After the operator installed and set up a steel wire rope, the other side of the beam crane pressed the water bottle with water bottle and water. Until the steel beam was separated from the transport boat, the beam crane slowly raised it to the design height and completed the steel beam pair. And lock. The steel beam on the other side of the main tower must also be set up later, so that the steel beams and main tower on both sides can maintain a strong balance of force like a balance.

After the steel beam stand is set up to complete the inside of the beam, it is also necessary to twist high -strength bolts, welded beam surfaces, and install cable cables. The setting process is long, the process is tedious and must be efficiently connected. The builders overcome the actual difficulties such as the hot weather, avoid high temperature periods, and speed up the construction progress early and late. It is understood that single -piece steel beams need to install 5828 sets of high -strength bolts, with 4,164 units located in the beam. This installation process alone requires more than 20 builders to take 2 to 3 days to complete.
